CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a division of U.S. patent application Ser. No.14/374,005 (filed Jul. 23, 2014), which is incorporated herein byreference in its entirety and is a national stage of InternationalPatent Application No. PCT/IB2013/051326 (filed Feb. 19, 2013), whichclaims the priority benefit of U.S. Provisional Application No.61/600,725 (filed on Feb. 20, 2012).

The present invention relates to antimicrobial compositions comprising abiocide in combination with an polyamine, a method for enhancing theantimicrobial activity of a biocides, and the corresponding use of suchaminopolymers as boosters for anti-microbial agents.

Antimicrobial effects of certain polymers containing quaternary ammoniumgroups has been described inter alia in WO06/117382, WO 97/32477.US-2011-171279 describes the antimicrobial activity of Triclosan, whichhas been chemically bonded to a polyethylenimine backbone.

It has now been found, that the antimicrobial action of common biocidesmay be greatly enhanced by addition of a polyamine.

The invention thus generally pertains to a composition comprising

a) an antimicrobial agent and

b) a polyamine, especially a polyethylenimine (PEI).

The antimicrobial agent (component a) is selected from the groupconsisting of chlorine dioxide, chlorine dioxide generating compounds,formic acid, and especially biocides containing halogen atoms, biocidescontaining phenolic moieties, and dialdehydes, as well as antimicrobialmetal such as antimicrobial silver or components containinganti-microbial silver.

Preferred polyamines (component b) are of Mw higher than 400 g/mol,preferred classes are polyethyleneimines (PEIs).

As used in the present invention, these polymers generally arepolycationic polymers or oligomers. Polycationic in the context of theinvention means that the polymer has a minimum charge density of morethan 1 meq/g, preferably from 5 to 25 meq/g, and more preferably from 10to 20 meq/g, measured in each case at a pH of 4 to 5.

In accordance with the invention it is possible to use all polymerswhich either comprise free or alkyl-substituted amino groups orquaternary ammonium groups in the polymer chain or carry secondary ortertiary amino groups or quaternary ammonium groups attached to thepolymer chain directly or via intermediate members. These amino groupsor quaternary ammonium groups may also be members of 5- or 6-memberedring systems, such as of morpholine, piperidine, piperazine or imidazolerings, for example. In accordance with the invention the cationicpolymer may be selected from polyamides, polyimines and polyamines,polydiallyldimethylammonium chloride, polyvinylamine, polyvinylpyridine,polyvinylimidazole, and polyvinylpyrrolidone, and also natural andsemisynthetic polymers, including cationically modified starch.

The polycationic polymers for use in accordance with the inventionpreferably have a number-average molecular weight in the range from 500to 2 000 000 g/mol, preferably 750 g/mol to 100 000 g/mol. Aspolycationic polymer (b) it is preferred to use polyethylenimine, thepolyethylenimine preferably having a number-average molecular weight of500 g/mol to 125 000 g/mol, and more preferably 750 g/mol to 100 000g/mol.

The polycationic polymers may be present in linear or branched form orin the form of what are called dendrimers; preferably they are presentin the form of dendrimers. Particular preference is given in accordancewith the invention to using polyethylenimine in dendrimer form. The termdendrimer relates to a series of branched molecular structures, interalia including dendrimers, star-like polymers and hyperbranchedpolymers.

Polyethylenimines of this kind are available, for example, under thetrade name Lupasol® from BASF SE. A more precise description of suchpolyimines is found, for example, in Macromolecules vol. 2, H.-G. Elias,2007 Vol. 2, pages 447 to 456.

One particularly preferred embodiment of the invention uses as said atleast one polycationic polymer polyethylenimine having a number-averagemolecular weight of 500 g/mol to 125 000 g/mol, preferably of 750 g/molto 100 000 g/mol, in dendrimer form.

In accordance with the invention at least one polycationic polymer (b)is used; hence there may be one polycationic polymer used or elsemixtures of two, three or more polycationic polymers.

A survey on typical synthesis methods for polymers suitable in theinvention may be found in C. Gao, D. Yan, Prog. Polym. Sci. 29 (2004),183. Dendritic and hyperbranched polymers, as useful in the presentinvention, are further described in P. J. Flory, J. Am. Chem. Soc. 1952,74, 2718, and H. Frey et al., Chemistry—A European Journal, 2000, 6, No.14, 2499.

An important embodiment of the invention relates to a compositioncomprising b) at least one ethylenimine homopolymer (also recalled aspolyethylenimine b).

In one embodiment, the polyethylenimine b) has a mean molecular weightM_(w) from the range 500 to 1000000 g/mol, especially 600 to 75000g/mol, more especially 800 to 25000 g/mol, as detectable by gelpermeation chromatography (GPC).

Highly branched polyethylenimines b) are characterized by their degreeof branching (DB). DB may be determined, for example, by ¹³C-NMRspectrometry, preferably in D₂O. DB is defined as follows:DB=D+T/D+T+Lwherein D stands for the fraction of tertiary amino groups, L (linear)stands for the fraction of secondary amino groups, and T (terminal)stands for the fraction of primary amino groups.

Highly branched polyethylenimines, as preferred as present component(b), are those polyethylenimines whose DB ranges from 0.1 to 0.95,preferably 0.25 to 0.90, more preferably 0.30 to 0.80, almost preferablyis 0.5 or higher, e.g. 0.5-0.8.

Most preferred are PEIs conforming in uncharged form with the(empirical) formula —(CH₂—CH₂—NH)_(n)— wherein n ranges fromapproximately 10 to 100000, most especially from 10 to approximately15000, and grafted variants thereof; end groups thus are predominantlyamino and/or moieties of the grafting agent. Grafting is especiallyachieved by ethoxylation. The PEI backbone is usually branched, i.e.certain N-hydrogen atoms in the above formula are replaced byCH₂—CH₂—NH₂ or by a further polyethylenimine chain, which again may bebranched, thus leaving the above empirical formula unchanged. PEIs are,under normal application conditions, e.g. in contact with water of pHclose to the neutral such as pH 4-9 or pH 5-8, usually present incharged form as polycationic polymers or oligomers. Examples are thefollowing species:

-   (I) Branched polyethylenimine of ca, molecular weight 800 (GPC) and    charge density of 16 meq/g of dry substance, determined at pH 4.5,    and ratio primary/secondary/tert. amino (as determined by    ¹³C-NMR)=1/0.9/0.5 (product commercially available as Lupasol® FG).-   (II) Branched polyethylenimine of ca, molecular weight 2000 (GPC;    hereinafter referred to as PEI (II)).-   (III) Branched polyethylenimine of ca, molecular weight 25000 (GPC),    charge density of 17 meq/g of dry substance, determined at pH 4.5,    and ratio primary/secondary/tert. amino (as determined by    ¹³C-NMR)=1/1.1/0.7 (product commercially available as Lupasol® WF).-   (IV) Ethoxylated polyethylenimine comprising 5 parts by weight of a    branched polyethylenimine core of molecular weight 600-800 (GPC) and    95 parts by weight of moieties of formula —CH₂—CH₂—O—; hereinafter    referred to as PEI (IV).

Antimicrobial compounds like those of present component (b) can beformulated into cleaning and disinfecting products. These may becleaning products for hard surfaces, laundry detergents, fabricconditioners, hand dishwash products, products for disinfection andsanitization of hard surfaces, all purpose cleaners, floor cleaners,glass cleaners, kitchen cleaners, bath cleaners, sanitary cleaners,hygiene rinse products for fabrics, carpet cleaners, furniture cleaners,but also products for conditioning, sealing, caring or treating hard andsoft surfaces. The cleaning and disinfecting products can be solids,powders, granules, cakes, bars, tablets, liquids, pastes or gels. Theymay be ready to use products, or concentrates which are diluted beforeor during the cleaning, washing, treating or conditioning process.

The purposes of the cleaning and disinfecting products containingBIOCIDE are the killing, control and/or inhibition of growth ofmicroorganisms, like bacteria, fungi, yeasts, viruses and algae on thehard and soft surfaces that are treated with the product. The BIOCIDEcan also have a benefit in the sense that it manipulates the metabolismof the mentioned microorganisms on these surfaces, which may result infewer odours. The effect can be a quick effect which takes place and isfinished within the treatment period. But the antimicrobial effect canalso be a longer lasting effect, which continues to take place on thetreated surfaces, after application.

Example 2

Preservation Challenge Test according to the test method for topicalproducts described in Eur. Pharm. edition 7.1 against several typicalbacterial or fungal spoilage microorganisms. A surfactant formulation(45% Cocoamidopropyl betaine in water) is preserved with 0.5%phenoxyethanol alone or in combination with 0.1% polyethyleneimine(referring to active ingredient).

Samples are inoculated with 1.5 to 3.5×105 cfu/ml as indicated in Table5 below. After 7 days of incubation at 20° C., samples are taken and thetotal viable count is determined. Log reductions are calculated withreference to the initial germ load. The results show that thecombination of phenoxyethanol with polyethylenimines perform better withregard to antimicrobial activity than phenoxyethanol alone. Table 4shows the composition of formulations, Table 5 shows antimicrobialefficacies (log red.) after 7 d of contact time.
